The Assad regime has taken more than a dozen towns and villages over last two weeks as it tries to consolidate control over more of the country

Syrian rebels are fighting to maintain territory amid a new government offensive to capture parts of the country’s last opposition strongholds.

The military moves threaten to torpedo cease-fire agreements in place since May and derail peace efforts. Over the past two weeks, about 100,000 people have been displaced in rebel-held Idlib province and neighboring areas in the northwest, according to the United Nations and humanitarian groups.
